IMPROVAEMENT IN JOURNAL-BEARINGS.

Specification forming part of Letters Patent No. 154,764, dated September 8, 1874; application filed April 7, 1874. v Y

To all whom it may concern:

Be it known that I, PARKER F. MOREY, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Iniprovement in J ourn al-Boxes, and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable others skilled in the art towhich my invention appertains to make and use the same, reference being had to the accompanying drawing, forming part of this specification, in which- Figure l is a vertical longitudinal lcentral section through the lower portion of a car-box embodying my said invention. Fig. 2 is a top View of the same, and Fig. 3 is a transverse section taken on the line .r x drawn across Figs. l and 2.

Similar letters of reference indicate like parts in the several figures of the drawing.

The object of my invention is to so construct the box as to allow the filling to come in contact with the -shoulders of the axle, and at the same Vtime allow the filling to be re-v moved When-Worn without injury to the shell ofthe box 5' and to that end it consists in providin g the shell, near the ends, with transverse grooves, within which are itted adjustable shoulders havingla series of channels, through which the il1ing;passes,forrning the shoulder bearing against .the shoulders of the axle, as will be more fully understood by the following description. l

In the drawing, A represents the shell or body of the box, which is made in the usual manner. B B are shoulders, which are loosely fitted into circular dovetail grooves formed.

across and within the walls Iof the box, as

shown in Figs. 1 and 2. These shoulders are arranged at a slight distance from the ends of the box, and are so shaped on their inner face p as to it the circumference of the axle, and are provided with a series of transverse channels, a a., as shown in Fig. 3. C is the iilling, which is made of the usual metals.

The shoulders B B are so fitted within the grooves as to admit lof being adjusted or removed when necessary. The object of the shoulders is to prevent the iilling from mov.

In constructing the boxl I usually make the body portion of ordinaryl cast-iron, consequently the same is much cheaper than when made from the material commonly used, and,

as the filling can be removed when worn and the body refilled, the box is more durableand convenient than those now in use.

Having thus described my invention, I claim- The adjustable shoulders' B B, provided with the channels a a, and combined with the block A and filling O, as and for the purpose specified.

The above specification of my invention signed by me this 17th day of January, 187 4.

PARKER F. MOREY.
